SEMINAR: Improving the Understanding of Distribution Grid Operations with Large Amounts of Distributed Energy Resources

SEMINAR: Improving the Understanding of Distribution Grid Operations with Large Amounts of Distributed Energy Resources

Seminar Abstract 

This talk will present several areas of ongoing research in the Renewables and Distributed Systems Integration Department at Sandia National Laboratories. Data requirements for distribution network numerical analysis, including the need for and availability of high-frequency photovoltaic (PV) generation and load measurements will be discussed. The method to improve secondary (transformer to customer) distribution grid models using advanced metering infrastructure (AMI) measurements and its success on actual feeders will be presented. Evaluation of distribution grid level PV and load forecasts will be presented including the implications for distribution grid planning and operations when incorporating the forecasts. There will be discussion of additional ongoing projects as time allows.

Seminar Speaker(s) 

Dr. Matthew Lave
Sr. Member of Technical Staff, Sandia National Laboratories, Photovoltaics and Distributed Systems Integration Department

Dr. Matthew Lave is a Senior Member of the Technical Staff in the Photovoltaics and Distributed Systems Integration Department at Sandia National Laboratories, where he has worked since 2013. Matthew is an expert at monitoring, analysis, and modeling of PV power production, both for performance assessment and for grid integration studies. Matthew has been first author on many peer-reviewed journal articles on topics such as solar resource assessment, PV performance modeling, solar variability analysis, optimal tilt angles for PV modules, and the impact of solar variability to electric grid operations. He developed the wavelet variability model (WVM) which is now widely used by researchers, consultants, and utilities for modeling the aggregate solar variability of distributed or utility scale solar plants. Recent work has included developing new methods for analysis of bifacial PV module performance, parameter and topology estimation of distribution grid secondary circuits (i.e., transformer to customer resistance and reactance), evaluation of PV forecasts’ performance and their value to grid operations, and leading development of the Grid Modernization Testing Network to make it easier to understand and partner with National Laboratory testing facilities and capabilities. 

Dr. Lave received his B.A. in Physics from Occidental College in 2008, and his M.S. and Ph.D. degrees in Aerospace Engineering from the University of California, San Diego in 2010 and 2012.
